p-values for comparison of OR were calculated using Fisher’s exact test
values were logarithmized to approach a normal distribution, values for the multivariable model were selected using a backwards selection process
OR = odds ratio, CI = confidence interval, IL-6 = interleukin-6, CRP = c-reactive protein, PCT = procalcitonin.
